SUIBSOIL-PLOW.

Specification of Letters Patent.

Patented May 19, 1914:.

Application filed April 15, 1912. Serial No. 690,834.

To all 1071 am it may concern:

Be it known that I, GEORGE XV. Srrnns, a citizen of the United States, residing at Caesar, in the county of Hancock and State of Mississippi, have invented certain new and useful Improvements in subsoil-Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sub-soil plows.

The object of the invention is to provide a simple, strong and efficient plow of this character composed of the minimum number of parts.

Another object is to provide a simply constructed and efiicient standard for support ing the plow point.

lVit-h these and other objects in view the invention consists of certain novel constructions, combinations and arrangements of parts, as will be hereinafter more fully described and claimed.

In the accompanying drawing Figure l is a perspective view of a subsoil plow constructed in accordance with this invention; Fig. 2 is a similar view of the plow standard; Fig. 8 is a similar view of the handle spacer and connecting member; Fig. 4 is a detail perspective view of the rear end of the plow beam.

In the embodiment illustrated a beam 1 is shown composed of a metal bar disposed edgewise and with its rear end bent laterally and then forwardly to form a seat 2 for the rear edge of the upper end of the stock or standard 3 which is also preferably formed of a metal bar. The lower end of this stock 3 is bent laterally at right angles to form a support 4 for the plow point 5 and its upper end is bent laterally in the opposite direction to form a flange 8 for engaging the upper face of the plow beam to relieve the connecting bolt of strain. The forward or front end of the beam 1 is preferably curved upwardly and is provided with longitudinally spaced apertures 6 for the clevis 7.

The sub-soil point 5 is preferably con structed as shown of a substantially flat plate with its front end inclined downwardly. This plate-like point rests on the laterally extending foot 4 of the standard and is secured thereto in any suitable manner,

preferably by bolts, the lower ends of which are arranged flush with the lower face of sa d foot to present a smooth surface to permlt the plow to run under the dirt without turning it. The seat 2 at the end of the beam holds the standard reliably against rearward movement and braces it, relieving the strain on the bolt 8 which connects said standard to the beam.

A pair of handles 9 of ordinary construction are engaged at their front ends with opposite sides of the beam 1 about midway its length and are secured thereto by a bolt. The inner faces of the front ends of these handles are preferably beveled to fit snugly against the sides of the beam and to cause the outer ends thereof to flare or diverge.

A spacing and connecting member for the handles is shown in the form of a triangular frame 10 composed of a metal bar bent in this form, one corner of the triangle being formed by the free ends of the bar which extend parallel for a short distance and straddle the rear end of the beam 1 and the upper end of the standard 3 and are secured thereto by a bolt or bolts 11 which pass transversely through said ends, beam and standard and securely bind them together. The bar or base of the triangle opposite the free ends of the member 10 extends between the handles 9 and the side members 12 thereof are secured to said handles. by bolting or otherwise, whereby said handles are spaced the proper distance apart and are braced against collapse. This member 10 also serves to rigidly connect the handles to the beam and standard and to hold the parts in their proper relative positions. Thus it will be seen that when the flanged upper end 3 of the standard 3 is engaged with the upper edge of the beam 1 and located in the hooked shaped seat 2 of the beam, the parts are properly positioned and by the employment of the yoke or frame 10, the handles 9 are not only strengthened and held in spaced relation to one another and properly supported but the standard and rear end of the plow beam are rigidly connected by a single bolt 11 which is passed through the ends of the yoke and the parts thus detachably and interlockingly connected. Thus it will be seen that a very strong sub-soil plow is produced composed of six parts only which includes the two handles.

I claim as my invention The combination with a plow beam and the plow, and a plow point attached to the lower bent end of the standard and projecting forwardly therefrom with one of its edges in contact with the standard.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
